ABSTRACT:
A stern fishing system utilizing a power block and purse seine net which is launched and retrieved from the stern of a fishing boat. When the net has been pursed, it may contain fish such as tuna, as well as a number of porpoises. For ecology reasons, the porpoise should be released unharmed. Such release is accomplished by driving the fishing boat forward so as to cause the edge of the net most aft of the fishing boat to be temporarily submerged permitting the trapped porpoise to leap from the confines of the net and back into the open sea.
